| | | | | | | | | | | | | | | | | | | | | | TclArgumentBCRelease, TclArgumentGet): * generic/tclCompile.c (EnterCmdWordIndex, TclCleanupByteCode, TclInitCompileEnv, TclCompileScript): * generic/tclCompile.h (ExtCmdLoc): * generic/tclExecute.c (TclExecuteByteCode): * generic/tclInt.h (ExtIndex, CFWordBC): * tests/info.test (info-39.0): Backport of some changes made to the Tcl head, to handle literal sharing better. The code here is much simpler (trimmed down) compared to the head as the 8.4 branch is not bytecode compiling whole files, and doesn't compile eval'd code either. Reworked the handling of literal command arguments in bytecode to be saved (compiler) and used (execution) per command (See the TCL_INVOKE_STK* instructions), and not per the whole bytecode. This removes the problems with location data caused by literal sharing in proc bodies. Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex).
* * generic/tclCompile.h: add support for debug logging of DTracedas2008-08-141-1/+4
| | | | | * generic/tclBasic.c: 'proc', 'cmd' and 'inst' probes (does _not_ require a platform with DTrace).
* * generic/tclBasic.c: Added missing release of extended commandandreas_kupries2008-07-281-2/+6
| | | | | | | | | | | | | | | word index when deleting an interpreter (DeleteInterpProc). Added missing ref count when creating an empty string as path (EvalEx). * generic/tclCompile.c (TclInitCompileEnv): Made same change to control flow as in TclEvalObjEx. Not needed while uplevel and siblings go through the eval-direct code path, however if that changes (like it did in 8.5+) better to have this in place instead of re-searching why certain places are without absolute locations. * tests/info.test: Added tests 38.*, exactly testing the tracking of location for uplevel scripts, and made the testsuite fully usable with and without -singleproc 1.
* * generic/tclBasic.c: Modified TclArgumentGet to reject pure listsandreas_kupries2008-07-231-16/+21
| | | | | | | | | | * generic/tclCmdIL.c: immediately, without search. Reworked setup * generic/tclCompile.c: of eoFramePtr, doesn't need the line * tests/info.test: information, more sensible to have everything on line 1 when eval'ing a pure list. Updated the users of the line information to special case this based on the frame type (i.e. TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new behaviour.
